Experimental Data
The solubilities of acetonitrile (1) and 1-octadecanol (2) in mass percent including the region of immisciblity over the indicated temperature range were reported in graphical form and in a table. Monotectic equilibrium occurs at 52.5°C (325.7 K, compiler). The upper critical solution temperature was extracted from the reported graphs by the compiler and found to be 63.6°C (336.8 K).
